[QUOTE="Vipersan, post: 948632, member: 325666"] So ..looks like we were right about Ka being DRO ... Much as I suspected in light of the XMWs superior hadling of low SRs.. Thanks for being the brave one Llew.. ;) Without extreme close ups of thre traces I would think difficult indeed to map out the circuit fully .. Plus there doesn't seem enough wiring to the many pins on the chips ...so I suspect dual sided pcb ..or even multi layered .. Looking again at your picture ..that xtal 25mhz ?? Is a long way from the front end of the lnb ...so possibly a clock generator for what may be a custom pic controller ..and or frequency division. For diseqc switching and signal processing ...??? Did you note the numbers on the chips ? ..or have they been obscured ? [/QUOTE]
